Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159566, here are decompositions:

  • 3 + 159563 = 159566
  • 13 + 159553 = 159566
  • 67 + 159499 = 159566
  • 97 + 159469 = 159566
  • 103 + 159463 = 159566
  • 109 + 159457 = 159566
  • 163 + 159403 = 159566
  • 229 + 159337 = 159566

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 159,566 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 159566 first appears in π at position 436,374 of the decimal expansion (the 436,374ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
